Any success with EcuFlash and F/I?

[D-VO]

Hello all. I've just installed a Kraftwerks SC on my car and tuning it myself with EcuFlash using OP2 for logging, and noticed there's some weird stuff going on with the port ratio table. I had originally set the Port Ratio tables to .25 (25%) for fueling 4400rpm and above and 1.00 g/rev and above, but on my log its showing there is no pulse width from the port injectors in those areas. Further, the AFR's are going pretty lean around 3000rpm and again at 4400rpm. I've attached a couple of logs for you guys to look at.

So far these are the tables that I've been fiddling with in an attempt to get AFR's back in range.

I also reduced the injector scaling and increased latency in an attempt to get the port injectors to add more fuel.

Any help would be great. Thanks!

Have you increased the engine load limits? What's the MAF Max g/s set to? There's also MAP compensations for PI that are worth looking at.

My Load limit is at 4.00 right now and the MAF limit is set to 300. Are you talking about the Port Injection MRP Compensation table? Nelsmar pointed that out to me so he helped me with the correction for that tonight.

Yeah, that's the one. Any further joy? I assume you have at least a rough MAF scale and that's not the cause of lean spots. It seems to be limit settings that prevent PIs from firing.

I was tuning the DI pressures and finally got a good run out of it; but now its too rich. I'm not quite sure if the OP2 logging for the Fuel Pressure is correct. Sometimes 20 psi is fine but other times I'm seeing 9.1:1 ratios. I'm gonna play some more on the way to work tomorrow.

*edit* Just noticed how rich it goes when it goes into open loop.
